Hi, I,lurk here a lot but rarely post. I have a musical fidelity integratrd as my main amp driving a pair af b and G corp radia 520 planar speakers. I was wondeing if anyone has opinions on good cheap subwoofers for music. I have considered SVS.Hsu, piinnacle digital, PSB,and kef psw 3000, but as these are hard to audition I really don't know how they will blend in with th the planars. Any oponin is appreciated. I live near chicago now, having moved for st louis
